摘要：
A valve system includes a load holding valve, a feed balancing valve, and a fast feed differential valve. The load holding valve may be in fluid communication with the load holding valve. The fast feed differential valve is configured to move between an engaged state and a disengaged state. In the engaged state the fast feed differential valve fluidly couples a ring side of a feed cylinder, the load holding valve, and a piston side of the feed cylinder to allow fluid to flow from the ring side to the piston side.
